Buildings account for around 30 percent of the world’s total energy consumption and a similar percentage of the world’s greenhouse gas emissions the main cause of climate change. The building sector is a major energy consumer, and empirical research reveals that carbon-dioxide emissions from the building sector exceed those of the industry and transport sectors. Contextual juxtaposition has commonly been applied in designing a new building in the historic district. In the realm of design, such philosophy-based design approach requires objective measurements. When new glass building considered, the question on greenhouse gas emissions becomes significant. To minimize energy consumption and reduce sun glare, brise-soleil and horizontal fixed shading devices have been used as elements of building’s facade. Nowadays, algae as part of building facade system have been used in creating a healthier indoor environment. This paper is written based on an on-going architectural design-based research on the use and role of algae as part of the building facade system. The new building of ITB Innovation Park is used as an infill project. With the help of modelling and extensive literature survey, this research will investigate how far the building (facade) design is affected by considerations on energy consumption pattern and environmental condition.

According to UNESCO Convention 1972, cultural heritage consists of tangible and intangible heritage. Soundscape has been considered as a part of the intangible heritage, and it refers to the perceptual quality. In the realm of built environment, perceptual qualities become important concerns, since cultural heritage cannot be described and appreciated using mono-sensorial analysis fundamentally based on vision. As perceptual construct, soundscape has been considered as a new approach in understanding the formation and design of sensitive urban environment. It is argued that perceptual quality, besides visual aesthetics, geographic, psychological and socio-cultural aspects, must be part of the considerations in architecture and urban design. Bandung is well-known for its urban heritage, and as former well-designed colonial town, the historic buildings and areas have morphologically constituted the structure of the inner city. However, the modernization and globalization have led to inevitable transformations, including the destruction of historic places and fabric/district of cultural significance. With the latest urban dynamics, urban environment has also experienced an inescapable process of “sound globalization”, which led to the losing of specific sound-marks in the respective area. This paper is based upon an ongoing research project on strategy for conservation of historic urban areas using soundscape approach. Methodologically, through sound walks, surveys and interviews, several notions relating to urban spatial and formal quality have been collected, assessed and interpreted. The result stands for the understanding of perceptual aspects and quality of urban space in historic urban areas that may contribute to the heritage conservation strategy.

In recent years, the upward trend of sea level rise caused by climate change continues to increase. This condition threatens urbanization that occurs in urban areas, especially in coastal area. Coastal is a strategic location for various activities such as ports, recreation, fisheries and agriculture, but it is vulnerable to changes caused by community and natural activities. Semarang is one of the coastal city located in the north of Central Java. Dense and slum settlements are dominating the coastal area of Semarang, one of them is fisherman’s settlement in Tambak Lorok. This area has been undergoing land subsidence for a long time and is now threatened by sea level rise due to climate change. The purpose of this study is to formulate adaptive urban design principles on land subsidence and sea level rise in Tambak Lorok, Semarang. This study is carried out with qualitative method using the approach of research and development in building a formula that applies to the conditions formed by land subsidence and sea level rise. The design principles formulated from this study are general principles that serve as guidelines for designing coastal areas that adaptive to land subsidence and sea level rise. We believe, the adaptation of urban space can reduce the impact of the disaster and create a resilient coastal area to reduce the risk of natural-induced disasters.

City center is an urban place which always attract people either for visit or work purpose. Those activities generates pedestrian traffic that needs to be managed by providing transition space. So far, the need of transition space in urban Indonesia has not been clearly regulated and considered related to the design of transition space that can be use by pedestrians in the city center. Furthermore, there are no studies related to the aspects that need to be considered in the design needs of urban transition space from pedestrians point of view. The study aims to design transition space requirements in the CBD through a visitor and worker pedestrian preferences approach.  Moreover, physical aspect / design element that need to be considered are conditions, potentials and factors that affect the existence of transition place. Field study and analysis found that visitor and workers found in Bandung central area mostly prefer pedestrian mall type as a transition space. Furthermore, the design principles for transition space consists of component of form, access and the character of space.
